The Tennessee Valley Authority has conducted water quality and biological monitoring in Chickamauga Reservoir from 1980 through 1984 as required by the National Pollutant Discharge Elimination System Permit for Sequoyah Nuclear Plant (SQN). Evaluation of 1984 operational monitoring data, comparison of these data to previous operational and preoperational data, and recommendations for continuation or discontinuation of each type of study are presented in this report. Plant operations, which were limited during the initial period of operational monitoring (1980 and 1981) because of plant testing, increased in 1982 and probably reflected ''normal'' conditions in 1983 and 1984. Comparisons of aquatic parameters upstream and downstream of SQN showed numerous differences among stations and/or over time. Most of these differences were considered unimportant or thought to be associated with factors other than SQN. Therefore, it is recommended that the following be discontinued: benthic macroinvertebrate community studies; mollusk bioaccumulation studies; fish impingement studies; fish gill net studies; and fish creel studies. Plankton studies should continue.
